Admission requires answering unpredictable probes for that shard within seconds — the probes arrive like a zephyr, never on a schedule an operator can script around. A missed probe suspends the identity until re-proven. For an attacker, every puppet costs a full shard of disk plus always-on bandwidth: 10,000 puppets mean 10,000 shards and 10,000 deadlines, and since no two shards overlap, one machine cannot cover for the rest.","stamp":3,"from":"poa1Gt787p6oVVzJzWbEUPbV2kxXJcjdEh1TTtZ9m1jgBfXr","nonce":1,"parents":["c781db3d6ee9e6b40a7bf99c48c1737abcf5a1c20694cee7b40d1887a03c5e95","c000730d5f9f755e47369b5a1e052d81383cce7c20255c6147bb42a7d45bc824"],"ts":1792879300,"cid":"poa-mainnet-1","sig":"4J5hQMJcrqHDCDC5kaf9pRzWn4PtSDAeBVoKg9DFDy5F53rUModHb4AeCxsbGkzeEEo8EAiW3ze1vg24thX4oPL8"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T19:29:23.388Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
